 Game Shark Codes 

Note: You must have a 3.0 or higher version of the Game Shark
to use these codes.

If you use an attack that you know will kill the opposing Pokémon, but will hit you
with the recoil, make sure that your Pokémon has at least 20 HP left. Use the
attack and you will not suffer the recoil damage.

Normal Pokémon are weak against Fighting types.
Fire Pokémon are weak against Water, Ground and Rock types.
Water Pokémon are weak against Electric and Grass types.
Electric Pokémon are weak against Ground types.
Grass Pokémon are weak against: Fire, Ice, Poison, Flying and Bug types.
Ice Pokémon are weak against Fire, Fighting and Rock types.

The "Import" feature and import pack can be used with Game Boy Game Shark codes while
playing the original game or codes designed for it.

While your Pokémon is doing their attack, hold Down + L and repeatedly press A.
Then when your Pokémon attacks, hold Down + L + A until the damage is taken. This
is very effective when you attempt a fatal attack. Note: This trick only works
between 80\% to 90\% of the time.

Successfully complete the Gym Leader Castle. Then when you want to complete it again, go
to the Gym Leader Castle, go directly to the Elite 4, and defeat your rival.

Upload Pikachu from the yellow version of the game to Pokémon Stadium. When
battling, Pikachu will say its name and have different motions for certain moves.
Note: You must go to battle for this to work. Do not register Pikachu.

When you start a new game, you can start with all three beginning Pokémon by
starting over and choosing one of them in the Game Boy Pokémon game. Then, capture
a Pidgey or Rattata. Save it to the boxes on Pokémon Stadium. Repeat the
steps with a different Pokémon until you get all three. You can also save and keep
Pokémon from your old game that you still want before starting over.

Place the desired Pokémon in a separate box from which you have your regular
Pokémon. Transfer that box to the 64box on the Nintendo 64. Shut off the system (if
you only have one transfer pak) and insert desired Game Boy pak. If you have two transfer
paks, then just switch the Game Boy pak with the one you are going to trade to. Then,
transfer the box with the Pokémon in it to the other Game Boy pak and you will have
the Pokémon without giving one in return.

Immediately after you choose a move and you want to go first instead of the CPU, hold L
and press A. Note: This trick only works about 50\% of the time, mostly in the Pika
Cup.

Successfully complete the entire Poké Cup to get a sticker on the GB Tower. This
will allow you play Pokémon on the Nintendo 64 twice as fast. If you beat the
Masterball in the Prime Cup, a "Superfast" setting will be unlocked in the GB Tower. The
title will change to "Doduo GB Tower". Press C-Left to activate it.

Put a box on the game, then put the Pokémon from a different game or the same one
in the box. Then, go back to the lab and put the box back on the game that you are trading
to, go to the box, and withdraw the Pokémon when you want or need it. Note:
This also works with items.

In one player mode with three CPU controlled opponents, successfully complete "Who's the
best?" five consecutive times on the hard difficulty setting within one match. Hyper will
be unlocked as a new difficulty setting for CPU controlled players.

Successfully complete the game.

Mew will become playable, as a "Rental" Pokémon, in the Round 2 version of the
game. He can only be played in the Prime Cup tournament, Gym Leader Castle, Free Battle,
and Mewtwo Battle modes.

Successfully complete Gym Leader Castle and Stadium modes. Then, Pikachu, Blastoise,
Charizard, Venusaur and Mewtwo will appear on the title screen.

6'8" limit and weight 44 pounds.
 

Poké Cup: Only can use 3 Pokémon, levels 50-55. The sum of the
